'71 Charger pwr brake car, 10" rear to 11" rear, What's needed?

[JG71B]

Is it as simple as swapping drums, backing plates and cylinders?

you have to pull out the axles to change out the backing plates
so you might need axle gaskets and to reset the axle end play with a dial indicator
after that it is simple as you say.

I'm dealing with this as well and im not sure its so simple. I have a 9.25 rear end with 11" backing plates but no brake parts. I don't want to tear into the axle so I bought new drums, shose, the plates that space the shose, parking brake actuators. I had bought a set of 10" parts where I think the cylinders are the same. But it's a lot of parts. If you are you going to bother with tearing into your axle for backing plates, my vote would be to go to discs.
